A urinary catheter with adjustable head opening size

Abstract

The invention discloses a urinary catheter which can adjust the opening size of the head end. The rear section is provided with an adjustment switch that can adjust the expansion and contraction of the guide wire. When inserting the catheter, the opening at the head end can be adjusted slightly smaller, and after indwelling, the opening can be adjusted larger or closed as needed. The invention adds the function of adjusting the size of the opening on the basis of the traditional urinary catheter, which facilitates drainage after the opening is enlarged, and prevents blood clots or tissue blocks from blocking the catheter; and can replace the traditional external clamping catheter by closing the opening at the head end. urinary catheter, thereby preventing retrograde infection of the urinary catheter. The invention has the advantages of simple structure, convenient manufacture and easy use.

Description

technical field [0001] The invention belongs to the technical field of clinical medicine and medical equipment, and relates to a catheter with an adjustable hole size at the head end. Background technique [0002] In recent years, the incidence of diseases such as benign prostatic hyperplasia and tumors, bladder tumors, and urinary stones has remained high, and has a tendency to increase year by year. These diseases require routine indwelling catheters after surgery, and bladder irrigation if necessary.
